BRACKET FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 453,248, dated June 2, 1891.

Application filed May 19,1890. Serial No. 352,337- (No model.)

To all whom, it may concern:

Be it known that I, THOMAS CARPENTER SMITH, a subject of the Queen of Great Britain and Ireland, and a resident of Philadelphia, Pennsylvania, United States of America, have invented certain new and useful Improvements in Converter-Brackets, of which the following isa specification.

Myinvention relates to brackets for electric wires, and particularly to brackets for suitably supporting sh unt-coils and the connecting-wires.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side view of a pole to which both brackets are applied. Fig. 2 is a similar view at right angles. Fig. 3 is an enlarged detail of the bracket and shuut coil box. Fig. 4 is a perspective View of the shunt-coil bracket. Fig. 5 is a detail of the shunt-coil box.

Like parts are indicated by the same letters in all the figures.

A A are the poles, having the cross-arms B B, to the outer end of one of which is secured the shunt-coil bracket. This bracket consists of the arms 0 O, with the vertical piece D. The arms carry the insulators E E, to which the main-line conductors F F are secured.

G is a shunt-coil box, having the insulators H H, whereby it .is secured to the vertical piece D by means of the screw-hooks J J. The conductors K K lead from the insulators E E down to the lamp, and loops L L from them lead into the shunt-coil. In like manner loops M M lead from the main conductors to the shunt-coil. At the junction of the arms 0 C and the piece D are the ledges NN, between which a place is formed for securing the entire device to the end of the cross-bar. The

loops or wires M M are connected within the shunt-coil box by a resistance, and each wire L is connected with its adjacent wire M within the box in the usual manner in such shuntcoil boxes. The resistance shunts sufficient current to the lamp below to sustain it.

Should the main line break at its insulators the loop-wire through the shunt-box will hold it up sufiiciently to keep the lights 011 the line going until proper repairs can be made. In the event of the breaking of the wires which lead to the lamp, if the break occurs at the top above the connection of the wire L with the wire K, the lamp below will not be extinguished,while if it breaks near the bottom of wire K the only disadvantage will be the extinguishing of that particular lamp. However, the invention has relation to the structure of the bracket and the COl'lllGClZlOIlS of the wires and posts rather than the operation of the lights.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. A bracket provided with two pairs of arms, each at right angles to the other, one pa r angular and adapted to receive the conductor-insulators, the other pair provided with screw-hooks adapted to receive the insulators upon which the sh unt-box is fastened.

2. The combination of a bracket with insulators for the main conductor, a shunt-coil secured to but insulated from said bracket, conductors connecting the coil with the main conductors, conductors connecting the coil with the lamp-loop, and conductors for the lamp-loop from the main conductors near the insulators on such brackets, substantially as described.
